What cam?
Is that the default Wilson Racing timing map now?
The ve table looks ok other than you need to modify the cells in the 2300-3200 range where the numbers get smaller as you go up the table. The reason these are still low on your map is because you currently can't spool fast enough to reach those cells as boost climbs...it just doesn't climb fast enough. That means you need to increase them manually to keep from having a lean condition in the future if load increases which makes boost build sooner (car full of people or stuff, going up a big hill wide open, etc.) or if you add a mod that increases airflow in the future.
They don't have to be perfect, just safer than they are now. I'd make the 2300 rpm column going up read 108 (100 fuel %), 115, 116, 116, 117, 117, 118, 118 (340 fuel %) for example. 2700 should continue to stay at 123 after the first 123 cell (140 fuel %), 3600 rpm column only need to change the 114 cell to 123.
In the same way, the numbers should also get bigger as rpm increases (left to right) until you reach the power peak, then they will taper lower. If you look at yours above 220%, they do this. Below that though, they don't because you have reached those cells during tuning. To reach them, you need to floor it starting at a higher rpm (I can tell you currently floor it around 2000 or so and let boost climb from there). If you start at 3500, 4500, etc it would raise the cells in the 100-140%/3600rpm+ range. You can change them all to 120 or so before you start your tuning session to ensure it's closer to safe before you start tuning it in that area.
The timing table is WAY too high at boost onset but we'll tackle that in the next post.

What did you break?
I had two questions in my last post, you didn't answer either one.

sorry stinger, the motor is stock, 84 xr4ti head and a 86 tc bottom end.. Scott set up new table when he sent it back to me,but iv played with ve analyzers live.. i have the fuel pressure set to 43 with the vacuum hooked up,75lb injector's here's what missed up

No flex pipe and not routed back into the downpipe? Double wammy of stress on the wastegate tube.
Why did VE live change the numbers so much, was it not properly tuned before? I see you didn't use any of my advise from my lengthy post above???
That timing table is very dangerous IMO but I'll save the detailed explanation until I can verify that you'll actually use my advise if I spend the time typing it out.

Read what I said above and you'll see that the changes to the "new" map aren't in the areas I was talking about. Since that was an untuned table that I used as a basis for the advice, the cells that need changed are the same location but the numbers in the cells will change a bit to match your new table numbers.

You just need to change the cells that don't match the pattern. See in column 2700 where it says 108, 112, 113, 105, 102, 110, 118? Clear there is a pattern of the numbers getting larger until the 105 and 102 and 110. Change those to larger numbers that fit the pattern (114, 115, 116 for example). Same theory for the 3200 and 3600 column, find the numbers that don't go up as fuel % goes up and make the pattern correct.
Also, you need a flex pipe in that wastegate dump tube (as stated above where you posted the broke picture, as well as on my site) or it will crack right back out.

Looks better. Only issues I see now are how the number columns go bigger, smaller, bigger, smaller as you go from 2300, 2700, 3200, 3600, 4000 in the 100-180 % fuel range.
They look ok when looking at each column vertically but not when compared to the columns next to it. Take a look at the sample Fuel VE table I posted in the Megasquirt tuning guide at the top of the FAQ section of this forum.

Looks like you picked up 4-5mph and cut .5 second of at the same boost as the videos. Did you change the timing to my map before this track session?
